CUSTOM is a universal design theme family for all basic Webasyst apps: Site, Blog, Photos, Shop-Script, and others. The parent (main) theme of the family, which includes the basic set of CSS rules and the common layout template index.html, is the CUSTOM theme for the Site app. All CUSTOM design themes used in other apps (e.g., Blog or Photos) utilize common CSS rules and file index.html of the parent (main) theme.

CUSTOM design themes are optimized for all modern web browsers and devices such as iOS and Android based devices. The layout automatically adapts to a device used by website visitor.

Webasyst is a CMS and an intranet combined. A suite of web apps for creating sites, blogs, online stores, and collaborating with your team — all in one place.
